SUPPORT STRUCTURE FOR SOLAR GENERATING APPARATUS < RTI ID = 0.0 >

The present invention relates to a solar photovoltaic power generation apparatus capable of floating a solar photovoltaic device on a surface of a water surface in a state of being fixedly supported in a stable manner, Structure.

Recently, research on alternative energy such as solar power, wind power, and tidal power has been actively conducted in preparation for depletion of fossil resources. Among these, photovoltaic devices that produce electricity using solar light have already been widely used.

However, in order to supplement the electric energy obtained through the existing power generation means through the solar power generation facility, there is a disadvantage that the solar power generation facility must be installed on a large scale, which requires a large flat land.

In order to solve this problem, attempts have been made recently to install a photovoltaic device on a wide surface of water. Specifically, a plurality of floats are connected to each other by supporting members, However, there is a problem in that it is not easy to fix the position and the angle for receiving the sunlight because the sunlight is often shaken by the waves as in the case of all floating bodies.

Therefore, in Patent Document 1, as shown in Fig. 1, a float 10 formed to float on the water surface as an area of a predetermined size, and a solar power generating facility 10 installed on the upper surface of the float 10 A support rope 40 for guiding the float 10 to be fixed to the pulley 30 and fixing the float 10 to the pulley 30; And one end of the support rope 40 is connected to an anchor 50 of a weight installed on the water floor and the other end of the support rope 40 is connected to the weight retaining weight 60, Has proposed a solar photovoltaic device.

That is, in Patent Document 1, the support rope is always tightly fixed by the tension weight for weight maintenance, so that the float on which the solar power generating facility is installed can be floated in a state of being fixedly supported on the water surface in a stable manner.

However, in the Patent Document 1, when the water level is lowered by the length of 'A', it comes into contact with the additional floor of weight, and when the floor comes into contact with the bottom floor as described above, the tension can not be maintained and the float is shaken by the waves do. That is, Patent Document 1 can only cope with the change of the water level below the length of 'A', and when there is a change in the water level above the length of 'A', the float can not be fixed properly on the water surface.

In addition, since the solar power generation facility installed on the upper surface of the float is fixed, when the floater is shaken, it is not easy to fix the position and the angle for receiving sunlight, resulting in a significant decrease in power generation efficiency.

The weight retaining weight 60 is a weight member that pulls the support rope 50 in a state of being always in a tight state and interlocks with the support rope 50 via the pulley 30.

The weight guide 70 is fastened (for example, coupled to one end) so that one end thereof is engaged with the weight retaining weight 60 and the other end is moved from one end of the support rope 50, So that the weight 60 can flow along the support rope 50.

2 and 3, even if the water level is lowered by a length of 'A', the weight retaining weight 60 does not contact the floor as shown in FIG. 3 (b) As shown in FIG. 5A, by moving to the side of the anchor 40, the tension can be maintained even when the water level changes beyond the 'A' length.
